hey.. totally lost... can any one give me a clear example of an aswer for the question
f(x)=2x^3-6X+7...
have to find their stationary points!?
Please help!!

The critical points where f'(x)=0 are called stationary points.

Start by finding the derivative of your function, set to 0 and solve for x.

Since it is just a cubic polynomial, it is easy to differentiate.
